removeMessages

protected void removeMessages(Collection<File> files)

logCompressionGains

protected void logCompressionGains(List<File> srcFiles,
                                   String minified)

Logs compression gains.

Parameters:

srcFiles - list of input files to compress

minifiedFile - output file resulting from the minify step

mkDir

protected void mkDir(File directory)

Creates the given directory (and parents) and informs the build context.

Parameters:

directory -

copy

protected boolean copy(File sourceFile,
                       File targetFile)
                throws IOException

Copies sourceFile to targetFile, making sure to inform the build context of the change.

Parameters:

sourceFile -

targetFile -

Returns:

true if execution was performed, false if it was skipped (because files did not change).

Throws:

IOException

merge

protected void merge(File mergedFile)
              throws IOException

Merges a list of source files. Create missing parent directories if needed.

Parameters:

mergedFile - output file resulting from the merged step

Throws:

IOException - when the merge step fails

haveFilesChanged

protected boolean haveFilesChanged(Collection<File> sourceFiles,
                                   Collection<File> outputFiles)

Parameters:

sourceFiles -

outputFiles -

Returns:

Whether any change was made to the source / output files. If not, then we can skip the execution of the current bundle.
